why are density and specific heat inversely proportional?
when a metal has a high density, it has a a low specific heat, and when it has a low density, it has a high specific heat. why is this?

the more heat applied to the metal, or any substance except water/ice, the less dense it becomes because the molecules spread farther apart than they would be when cooler.
specific heat is the amount of heat required to raise the temperature of 1g of a metal (anything) 1ºC or 1K. if we have W, tungsten, with a density of 19.35 g/cc, its specific heat = 0.13 J/g-C, it takes very little heat to raise the temperature 1C because of the tightly packed atoms. on the other hand, a metal such as Li, lithium, which has a density of 0.534 g/cc. its specific heat is 3.582 J/g K. it takes more heat to raise the temperature of Li 1C because of the more loosely packed atoms.

If i will keep in mind, the density is the mass divided by employing the quantity. particular warmth is the warmth potential divided by employing the multiplication of the mass and the replace in temperature. it might appear like: q = C / (mass)(replace in temperature). i do no longer undergo in innovations the relationship between density and the particular warmth. i'm hoping that plenty helps.
